Problem $5$:

An array of edge dislocation is shown below. Assume the dislocation at the origin is unable to move, the remaining dislocations can glide on their slip plane. How would each of the dislocations drawn in the figure below move in the stress field of the dislocation at the origin $($neglect interaction of mobile dislocations and only consider two dislocation problems$)?$ Also positive and negative dislocations have a Burgers vector of $\frac{?}{\text{b}\text{a}\text{r}}(1)00$ and $100,$ respectively.
